They are really different then most kinds<span />
Answer:
The situation in which some individuals have greater reproductive success than other individuals in a population. Along with variation and heritability, it is one of the three conditions necessary for evolution by natural selection.
There are so many factors that contributed to this over time, reproductive success differs and it could be attributed to hereditary and variation as well. Most often, the hereditary plays the most role out of all as the viability of both eggs and sperms could have been inherited from parents or being affected as a result of environmental factor or nutrition or other factors.
For instance, if one has a rhesus factor of negative and went ahead to marry another male counterpart with negative rhesus factor, this sedomly leads to miscarriage which could have been controlled had it been they were thoroughly counseled. Furthermore, physical factor such as accident could damage one spermatical vessicles that houses the sperm cells which render such an individual to be unable to donate a viable sperm cell for reproduction.
Those with high rate of reproductive success thrives as result of having many offspring which increases their chances of having more offspring than those with little success rate.
Explanation:
Answer: True
Explanation: Like all living things, prokaryotes need energy and carbon. They get energy from inorganic chemical compounds.
Chemoautotrophs are organism that utilizes inorganic molecules to supply energy for the organism, and use carbon dioxide as a carbon source. Chemoautotrophs are mostly prokaryotes that break down hydrogen sulfide and ammonia.
Most Eukaryotes cannot utilize these inorganic molecules as energy source.
Answer:
The initial amount, 1.3 million = 1,300,000 is the 100%.
now, 640,000 is a given percentage (lower than 100%) of that.
How we can find it?
suppose that 640,000 represents an x%.
Then we have that the quotient between the actual quantities and the percentages must be the same
(640,000/1,300,000) = x%/100%
x% = (640,000/1,300,000)*100% = 49.23%
Then the percentage declined is:
100% - 49.23% = 50.77%
The other question can not be answered with the given information.
